I've got a 3" japspeed full system and fancy swapping the back box to a straight out the back style (can't think of the name lol) as apposed to the jap style one. What options do I have? Cheers.

Hmm subscribed.

Got prodrive box atm but mapper said it should probably on my list of things to change if I want more power. I love the aesthetics of it though.

 

I just fancy a change really. It's been mapped with the exhaust so would like to stick with the current set up with a change in backbox. Oh and it's a p reg classic import btw.

 

I have Japspeed shotguns exiting my rear bumper No back box just a twin pipe from center section

 

Why not have a look at a Hayward & Scott or a miltek system?

 

I'm going to hazard a guess and say that's loud? Lol

 

You want something like team ice back box or scoobyworld afterburner extreme

 

Needs to be track friendly too mate, trackday at oulton next month (105db)

 

When you say straight out the back do you mean no box at the rear or non angled tail pipe?

 

Non angled mate.

 

Ah I got mixed up there sorry, though you meant no silencer back box! Ignore the brands I mentioned above!

 

Ha ha ok mate, prob my crap explanation

 

Or in just tired miltek sound nice and look nice, not over loud so should pass track nose limits!

 

Yeah maybe lol. I'm guessing you can buy the miltek backbox seperatly? Will keep an eye out for something second hand as I just want to trial and error something.

 

When its cold, it is pretty loud but once it warms up its not too bad. It is louder than the normal scoob and its got a different sound too it I did put a video clip on here of it a while ago

 

I went for this for the same reason , track friendly ... It's a very nice kit . TSL Group N

 

We have a straight one 2.5 or 3" on the site

I can also supply a load of others from 2.5" up to 5"

What car is it going on?

 

Is that the one you have for sale or did have? I think mine will be fine ref db level as I don't think it's as loud as my Clio was (103db).

 

Looks great but way over what I want to spend I'm afraid. Just after something to experiment with really.

 

Go for it, the bigger back boxes (I have an Afterburner) makes a huge and very pleasurable difference.

 

Would a straight cut one reduce noise, I guess it will alter it depending on which one i went for?

 

Have a look on Cobra Sports I am currently uploading the new products to the site I can do a small discount on their RRP

Was really looking for a cheap and cheerfull replacement tbh but thanks.

 

I don't think that you can go far wrong with the prodrive set up. Loud enough when putting your foot down, but quiet enough not to upset the neighbours when starting up. An example below

 

Hmmmm I like the look of the inward rolled one.

Anyone got any pics of that?

 

I think that the Japspeed centre section is only designed to match up with their backbox ?

I have a newage 3" Japspeed CAT back system and the centre section is too short to mate up with the APS backbox I tried.

I compared the Japspeed exhaust to the standard set up as well and it appears that the backbox is 'longer' than the standard one but the centre section is shorter.

 

Thanks for that mate. I may just end up keeping mine tbh, nothing wrong with it but like I've said there's nothing wrong it.

 

No worries mate, you know where I am if I can help with anything

Send me a direct link mate and I'll see if I can get you some photos.
